The position of the particle moving along `Y`-axis is given as `y=At^(2)-Bt^(3)`, where `y` is measured in metre and `t` in second. Then, the dimensions of `B` are

A

`["LT"^(-2)]`

B

`["LT"^(-1)]`

C

`["LT"^(-3)]`

D

`["MLT"^(-2)]`

Text Solution

Verified by Experts

The correct Answer is:
C
As, `y=B["T"^(3)]Rightarrow["L"]=B["T"^(3)]RightarrowB=["LT"^(-3)]`
